Two experiments were conducted over 3 yr to determine pregnancy rates in beef heifers after a timed AI in response to the 7-11 Synch protocol. In Exp. 1, 179 heifers were either fed melengestrol acetate (MGA; 7-11 Synch) or given an intravaginal progesterone (P4)-releasing insert [controlled intravaginal drug releasing device (CIDR); 7-11 CIDR] for 7 d. Prostaglandin F2αwas administered on the ...

Progesterone exerts beneficial effects on the human cardiovascular system by inducing rapid increases in nitric oxide (NO) production in vascular endothelial cells, but the receptors mediating these nongenomic progesterone actions remain unclear. Using human umbilical vein endothelial cells (HUVECs) as a model, we show that progesterone binds to plasma membranes of HUVECs with the characteristi...

(1) Dear Alice, I heard that while it's generally not advised to take antibiotics while on the birth control pill, it's still okay to take tetracycline. Is this true? (2) Dear Alice, I have heard many many times that antibiotics interfere with the effectiveness of oral contraceptives, but what about the depo-provera shot?

This study was conducted to determine the effect of progestin source on some reproductive performance, lamb birth weight and mortality rate in Akkaraman ewes. A total 40 sheep breed with similar body (51.3 ± 1.5 kg) at least two parturitions were used as experimental animals. In all ewes, intramuscular injection PGF2α (2.5 mg) administered 96 hours before estrus synchronization obtain corpus lu...

BACKGROUND Many family health innovations that have been shown to be both efficacious and cost-effective fail to scale up for widespread use particularly in low-income and middle-income countries (LMIC). Although individual cases of successful scale-up, in which widespread take up occurs, have been described, we lack an integrated and practical model of scale-up that may be applicable to a wide...

Dairy cows that are being cared for in family businesses were used to compare the pregnancy rates by applying different time periods, using progesterone devices, and fixed-time artificial inseminations. The randomly divided into 3 groups. Group 1(n = 56); On day 0, GnRH (IM) (10mg Buserelin acetate, Ovarelin, CEVA DIF) + Progesterone implants (PRID®) (1,55 g CEVA), Day 8 PGF2α (Dinoprost tromet...

RATIONALE Endometrial cancer patients with lung metastases are rare, and more rarely with long-term management of progesterone after recurrence. PATIENT CONCERNS Informed consent of the patients and their families. DIAGNOSES Endometrial cancer (IVB) (Refer to 2009 FIGO stag of endometrial cancer). INTERVENTIONS the patient was treated with Megestrol Acetate Dispersible Tablets (trade name...
